The ST. CLAIR signature style is traditionally fitted on the bust & waist & generously cut to be loose over the hips. 

Every style is cut differently and more specific details can be found in the 'notes' section of each product page. Please help minimise returns by using our measurement guide to determine which ST. CLAIR size will best fit you, before you buy.
